(Conventional technology) Pipe supports with trestles and jacks are used for formwork shoring that supports slab formwork and beam formwork in buildings, etc., and pipe supports are used in buildings with low floor heights. Although it is often used, in cases where the floor height is high, a pipe support made of a round pipe with a jack built in is not strong enough, so recently temporary supports made of a strong square pipe with a jack built in are being used. It has become like that. Similar to shoring using conventional pipe supports made of round pipes, this shoring using temporary supports is made by connecting the temporary supports to each other with connecting materials.

(Problem to be solved by the invention) Conventionally, the connection between the temporary support and the connecting material was
For example, a steel pipe clamp is fixed to the temporary support via a fixture, and a connecting material is tightened to the clamp. Therefore, when erecting temporary supports, it is necessary to tighten the connecting materials while keeping each temporary support vertical, which not only requires a lot of manual labor, but also makes the work troublesome. During construction, special equipment such as vertical measuring equipment is required.
There were many economic problems.

The present invention eliminates these drawbacks of conventional shoring, and allows the mutual connection of temporary supports to be made easily and reliably at any position above or below the temporary support without requiring any effort, making the temporary installation of shoring efficient and economical. The purpose of the present invention is to provide a device for connecting temporary supports.
